FRUIT-PARING MACFHNE.

SPECIFICATION forming part of Letters Patent 130,340,937, dated April27, 1886.

Application filed September 21,1885. Serial No. 177,729. (No model.)

T0 at whom it may concern:

Be it known that I, HERBERT COTTRELL, a citizen of the United States,and a resident of Newark,county ofEsseX, and State of New Jersey, haveinvented a new and useful Improvement in Fruit-Faring Machines, of whichthe following is a specification.

My invention relates to a rotary cutter for fruit-paring and to themeans employed to actuate it,

My object is to provide simple and effective means for supporting thecutter-spindle. and for guiding the movement of t-heannular cuttertoward and away from the fruit during the process of paring and afterits completion. I secure this object by journaling the rotary spin dle,which carries the cutter in a supportingarm, and imparting to said arm avariable movement by means of a stationary eccentriccam,which ittraverses, by mechanism hereinafter described.

Figure 1 represents a front elevation of my improved parer. Fig. 2represents a plan View. Fig. 3 represents a plan view of thesupporting-arm and the cutter-spindlc which revolves therein detached.Fig. 4 represents a cross-section of the arm and cutter-spindle drawn online Y Y of Fig. 3. Fig. 5 represents a cross-section of the arm andspindle drawn on line X X of Fig. 3.

Like letters and figures indicate like parts.

Z is the main frame, carrying the several gear-wheels which actuate theannular cutter 2 and rotary fork T, having tines l0. JDh-e fork isrotated through action of driving-wheel M, intermediate gear-wheel,N,and gear-wheel O, the lastnamed wheel being rigidly secured to thebase of the fork-spindle T at 18. cutter-spindleBreceivesitsvariablemovement around cam F through drivingwheel M, spindie 14,spur-wheel I, and wheel G, with which the spur-wheel gears. Thesupporting-arm O is journaled on the face of said wheel G atD D, (shownin Figs. 1 and 3,) and held in its bearings by plate The bearing of thesupporting-arm 0 against the cam F is secured by spring 9, one end ofsaid spring being secured to the arm 0 at 4, the other end to the centerof the cam F.

It will be seen that the rotation of the wheel The G will carry thesupporting-arm of the cutterspindle 13 around the cam F, and therebyimpart to it the required movement toward and away from the fruit.

WVhile the supporting-arm Cis being carried around the cam F the annularcutter 2 is being revolved on its own axis or spindle B. This rotarymovement is imparted through driving-wheel M, pinion V, spindle L,having bearings in projecting studs 11 and 12, gearwheels K and H, thelatter loosely journaled on the camsupport and communicating a rotarymotion to spindle B through pinion E, carried on the end thereof.

15 is the handle, rigidly attached to driving wheel M.

S is the standard which supports the machine. This standard is securedto the frame Z by means of a dovetail socket, into which it fits, andtothe table by means of aflanged foot and clamping-screw 19 connectedtherewith.

The supporting-arm (3 and parts connected therewith are best shown inFig. 3. The form of the arm is that of a half-sleeve longitudinally,having covered bearings for spindle B at 7 and 8. The outer end of thearm forms the guard 3, which governs the depth of the out while paring.I

A is the cutter-head, carried by spindle B, and 2 the annular cutterthereon.

5 is a slotted piece held by set-screw 6to the projecting plate 4, madepart of arm 0. This piece 5 projects under and nearly touches theannular cutter when in place. Its function is to prevent the cutter fromleaving the cutterhead and its inner surface from being clogged by thefruit-skins during the process ofparing.

The annular cutter2 is simply a strip of thin steel having one of itsedges sharpened,and so bent in circular form as to adapt itself to theannular groove in the cutter-head A by its own elasticity. The two endsof the circular strip are kept sufficiently apart on the cutter-head toenable the sharp-edge angle of one end to come in contact with the fruitas the cutter re- Volves.

of the out. By this form of cutter the tendency to scrape the skinwithout cutting, noticeable in paring peaches with a rotary knife havinga continuous cuttingedge, is entirely removed.
